Franklin K. Van Zandt, 77, a retired cartographer and surveyor with the U.S. Geological Survey who also worked with the Agency for International Development in Bogota, Columbia, died Sunday at Northern Virginia Doctors Hospital following a heart attack. He lived in Oakton.
Mr. Van Zandt was born in Oakland City, Ind., and grew up in Spokane, Wash. He earned a bachelor's degree in civil engineering at Washington State University.
He began his career with the U.S. Geological Survey in 1927 and worked on field mapping in the western and central United States. In the 1930s, he was transferred to Chatanooga, Tenn., to work with the Tennessee Valley Authority. While there, he assisted in the development of photogrammetry, the use of aerial photographs in map making.
Mr. Van Zandt was transferred to Washington in 1941 and remained here until the United States entered World War II. He then served as a captain in the Army Corps of Engineers.
His postwar career with the survey included an assignment with the Inter-American Geodetic Survey in the Panama Canal Zone in 1956.
In 1963, he moved to AID and was assigned to its mission in Bogota, Colombia, as a mapping consultant. In 1965, he returned here, rejoining the survey for a brief period and retired in 1966.
For the next seven years, Mr. Van Zandt was employed by the Pennsylvania Bureau of State Parks to survey the state's park system. He moved back to the Washington area in 1973 and was engaged by the Geological Survey to prepare for publication "Boundaries of the United States and the Several States."
Mr. Van Zandt was a member of the American Society of Civil Engineers, the Society of American Military Engineers, the American Society on Surveying and Mapping, the American Society of Photogrammetry and Tau Beta Pi, an honorary engineering society.
He also was a member of the National City Christian Church in Washington and had been an elder and chairman of its Official Board.
Survivors include his wife, Helen, of Oakton; three daughters, Eleanor Van Zandt of London, Elizabeth Helen Van Zandt of Richmond, and Martha Fickett of Richmond, and one grandchild.
The family suggests that expressions of sympathy be in the form of contributions to the National City Christian Church Restoration Program, Thomas Circle, Washington, D.C., 20005.
